Question 2

appendicular skeletal

Answer 2

pectoral gridle (shoulders), upper and lower limbs(arms and legs), pelvic gridle(hip bones)

Question 4

muscles

Answer 4

generate motion, force. 3 types of muscle tissue occur skeletal, cardiac and smooth

Question 5

cardiac muscle

Answer 5

only in heart and responsible for moving blood through the circulatory system by allowing the heart to contract rhythmically

Question 6

smooth muscle

Answer 6

primary muscle of internal organs, tubes and influences the movement of material in, out and within the body

Question 8

compact bone

Answer 8

hard outer layer of bones, minimal gaps and spaces. contains haversian canals

Question 9

spongy bones

Answer 9

fills the interior of bones, an open cell porous network

Question 10

osteocytes

Answer 10

contain nucleas and cytoplasm. most common in mature bones play important role in all aspects of bone function

Question 11

osteoblasts

Answer 11

responsible for bone formation, constantly being reshaped by these cells

Question 12

osteoclasts

Answer 12

instrumental in controlling the amount of bone tissue. removes bone tissue by demineralizing the matrix

Question 13

tendons

Answer 13

connects muscle to bone. tough, flexible fibrous connective tissue

Question 14

joints

Answer 14

structures that connect individual bones and may allow bones to move against each other to cause movement. most common movable joint is synovial

Question 15

ligament

Answer 15

connect ends of bones together in order to form a joint. small band of white, fibrous elastic tissue.

Question 16

bursa

Answer 16

small fluid filled sac made of white fibrous tissue and lined with synovial membrane. provides cushion between bones and tendons
